Metatorial offers a great selection of papers regarding content management on their site. The papers are great discussions on the subject of CM. The site also offer interviews, a great CM poster, and a promo for the Content Management Bible.

This site is unfortunately a great poster child for why one should not use frames. Frames make pointing to the desired content far more difficult than it needs to be. If people link directly to great content they lose the site's links to their other great resources. This site is horribly frustrating as there is great content wrapped in the absolutely wrong method for presenting great information to be shared. I guess folks can't be great at everything, I know I am not.
